本考案は、ダイカストマシン等、油圧により動作する油圧利用装置におけるそ の作動油の温度管理装置に関するものである。 The present invention relates to a temperature control device for hydraulic oil in a hydraulically utilizing device such as a die casting machine which is hydraulically operated.
【０００２】[0002]
油圧利用装置における作動油は、その温度が高くなると粘性が低くなってシー ル部から漏れやすくなるだけでなく所定の圧力が出なくなり、逆に温度が低くな ると圧力にバラ付きが生じやすくなるため、適正な温度管理が必要となる。 When the temperature of the hydraulic oil utilizing device becomes high, the viscosity becomes low and it is easy for the hydraulic oil to leak from the seal part, and the prescribed pressure is not released. Conversely, when the temperature becomes low, the pressure tends to vary. Therefore, proper temperature control is required.
【０００３】 しかし乍ら、ダイカストマシンの場合でいえば、アンロード時に作動油を冷却 用クーラーに導入させているだけで格別な温度管理は行なっておらず、従って、 アンロード時間が短い場合には作動油が冷えきれずに温度が高くなってしまい、 またマシンの立上り時（動作開始初期時）には作動油の温度が低いため鋳造サイ クル（動作）のバラ付きが発生する等の不具合があった。However, in the case of a die casting machine, however, no special temperature control is carried out simply by introducing the hydraulic oil into the cooling cooler at the time of unloading, and therefore, when the unloading time is short. Causes the temperature of the hydraulic oil to rise without being able to cool down, and the temperature of the hydraulic oil is low when the machine starts up (the initial stage of operation start), causing variations in the casting cycle (operation). was there.

以下、本考案実施の一例を図面に基づいて説明する。 図中Ａは、従来から使用されている作動油の冷却用回路であり、油圧ラインか らの戻り油を貯留しておくための作動油タンク１と、ロード時（圧油供給時）に 作動油タンク１内の作動油をポンプ２を介して油圧ラインへ圧油を供給するため のローディングマニホールド３と、アンロード時に作動油を冷却して作動油タン ク１へ戻す作動油冷却用クーラー４とで構成されている。 An embodiment of the present invention will be described below with reference to the drawings. In the figure, A is a hydraulic oil cooling circuit that has been conventionally used. It is a hydraulic oil tank 1 for storing return oil from the hydraulic line, and it operates when loading (supplying pressure oil). A loading manifold 3 for supplying hydraulic oil from the hydraulic tank 1 to the hydraulic line via the pump 2, and a hydraulic oil cooling cooler 4 for cooling the hydraulic oil to return it to the hydraulic oil tank 1 during unloading. It consists of and.
【０００７】 そして、本考案に係る作動油の温度管理装置Ｂは、上記作動油タンク１内の作 動油温度を観測するための温度センサー５と、その温度センサー５からの指令に 基づいて作動油タンク１内の作動油を循環撹拌するためのポンプ６と、該ポンプ ６と作動油タンク１との間に介在設置して上記温度センサー５からの指令に基づ いて作動油を冷却するための補助クーラー７とで構成される。The temperature control device B for hydraulic oil according to the present invention operates based on a temperature sensor 5 for observing the temperature of the hydraulic oil in the hydraulic oil tank 1 and a command from the temperature sensor 5. A pump 6 for circulating and stirring the hydraulic oil in the oil tank 1, and installed between the pump 6 and the hydraulic oil tank 1 to cool the hydraulic oil based on a command from the temperature sensor 5. It is configured with the auxiliary cooler 7 of.
【０００８】 温度センサー５には、指令機能を備えた（デジタル）温度計８を接続せしめ、 その温度計８を作動油タンク１内の作動油を循環撹拌するためのポンプ６並びに 補助クーラー７にそれぞれ電気的に接続する。A (digital) thermometer 8 having a command function is connected to the temperature sensor 5, and the thermometer 8 is connected to a pump 6 and an auxiliary cooler 7 for circulating and stirring the hydraulic oil in the hydraulic oil tank 1. Connect each electrically.
【０００９】 ポンプ６は、作動油タンク１と循環ライン61を介して連通接続させると共に、 補助クーラー７と入ライン62を介して連通接続せしめ、且つ補助クーラー７の出 ライン71を作動油タンク１に連通接続させる。The pump 6 is connected to the hydraulic oil tank 1 via a circulation line 61, and is connected to the auxiliary cooler 7 via an inlet line 62, and an outlet line 71 of the auxiliary cooler 7 is connected to the hydraulic oil tank 1 Connect to.
【００１０】 また、ポンプ６から補助クーラー７へ通じる入ライン62と補助クーラー７の出 ライン71には、必要に応じて作動油を温めて作動油タンク１へ循環させるための ヒーター９を介在設置し、入ライン62の切換弁10を温度センサー５の温度計８と 電気的に接続させる。In addition, a heater 9 for warming the working oil and circulating it to the working oil tank 1 is installed in an inlet line 62 leading from the pump 6 to the auxiliary cooler 7 and an outlet line 71 of the auxiliary cooler 7. Then, the switching valve 10 of the inlet line 62 is electrically connected to the thermometer 8 of the temperature sensor 5.
【００１１】 而して、作動油タンク１内の作動油温度が設定温度近くにまで高くなると、温 度センサー５からの信号により温度計８にその時の温度が表示されると同時に、 ポンプ６にその旨の指令が発せられる。すると、ポンプ６が動作して作動油タン ク１内の作動油が循環ライン61からポンプ６を通して循環撹拌され、その結果、 作動油タンク１内の作動油の温度が均一化させる。When the temperature of the hydraulic oil in the hydraulic oil tank 1 rises to near the set temperature, the temperature from the temperature sensor 5 is displayed on the thermometer 8 at the same time, and at the same time the pump 6 is displayed. A command to that effect is issued. Then, the pump 6 operates and the working oil in the working oil tank 1 is circulated and stirred through the circulation line 61 through the pump 6, and as a result, the temperature of the working oil in the working oil tank 1 is made uniform.
【００１２】 また、なお作動油タンク１内の作動油温度が上昇する場合には、温度センサー ５からの信号指令によって、ポンプ６並びに補助クーラー７へ冷却水を供給する ための冷却水流入調整弁11が動作し、作動油タンク１内の作動油が入ライン62を 通って補助クーラー７へ供給されると共に、作動油の温度に応じて冷却水流入調 整弁11の開度が自動的に調節されて、補助クーラー７の出ライン71から作動油タ ンク１内へ適正温度の作動油が循環供給され、その結果、作動油タンク１内の作 動油の温度が設定温度に維持されるようになる。Further, when the temperature of the hydraulic oil in the hydraulic oil tank 1 still rises, a cooling water inflow adjusting valve for supplying cooling water to the pump 6 and the auxiliary cooler 7 in response to a signal command from the temperature sensor 5. 11 operates, the hydraulic oil in the hydraulic oil tank 1 is supplied to the auxiliary cooler 7 through the inlet line 62, and the opening degree of the cooling water inflow adjustment valve 11 is automatically adjusted according to the temperature of the hydraulic oil. The hydraulic oil having the proper temperature is circulated and supplied from the outlet line 71 of the auxiliary cooler 7 into the hydraulic oil tank 1, and as a result, the temperature of the hydraulic oil in the hydraulic oil tank 1 is maintained at the set temperature. Like
【００１３】 そして、更に作動油温度が上昇し続けて設定温度以上になった場合には、温度 センサー５の温度計８に接続した警報器12が動作して、警報を発するようになる 。When the temperature of the hydraulic oil continues to rise and exceeds the set temperature, the alarm device 12 connected to the thermometer 8 of the temperature sensor 5 operates and issues an alarm.
【００１４】 また、マシン（油圧利用装置）の立上り時（動作開始初期時）等、作動油の温 度が設定温度よりも低い場合には、温度センサー５からの指令によって、ポンプ ６から補助クーラー７へ通じる入ライン62の切換弁10が切り換り、作動油がヒー ター９を通って温められて出ライン71を通って作動油タンク１へ循環するように なる。When the temperature of the hydraulic oil is lower than the set temperature, such as when the machine (hydraulic pressure utilization device) starts up (at the beginning of operation), the pump 6 receives an instruction from the temperature sensor 5 and the auxiliary cooler. The switching valve 10 of the inlet line 62 leading to 7 is switched, the working oil is warmed through the heater 9 and circulates through the outlet line 71 to the working oil tank 1.
【００１５】[0015]
本考案の油圧利用装置における作動油の温度管理装置は斯様に構成したので、 作動油タンク内の作動油を容易に常時適正な温度に維持管理することが出来る。 従って、ダイカストマシン等の油圧利用装置を安定適正に動作させることが出 来るようになる。 Since the temperature control device for hydraulic oil in the hydraulic utilizing device of the present invention is configured in this way, the hydraulic oil in the hydraulic oil tank can be easily maintained at an appropriate temperature at all times. Therefore, it becomes possible to stably and properly operate the hydraulic utilizing device such as the die casting machine.
